Answer:
27.2
Step-by-step explanation:
Hello!! I for got how to solve this but, I think it is:
68 x 0.60 = 40.8
68 - 40.8 = 27.2
Explanation:
Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.
So far... we know that:
Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.
Answer:
∠2 = 40
∠11 = 60
360 / 20 = <span>18°
i don't know if that is right</span>

Answer:
The integers are 11 and 12.
Step-by-step explanation:
Let x be the greater integer, then the lesser is x - 1, so:
2x = 3(x -1) - 9 Distribute the 3:
2x = 3x - 3 - 9 Subtract 3x from both sides:
-x = -3 - 9
-x = -12
x = 12.
